Sushi Bar Cupful is a term that refers to a combination of three items commonly found in a sushi bar: SAKE, green tea, and pickled ginger. SAKE is an alcoholic beverage made from fermented rice, green tea is a type of tea made from the leaves of the Camellia sinensis plant, and pickled ginger is a condiment made from ginger root that has been pickled in vinegar. Together, these three items form a traditional accompaniment to sushi.
